SCRAPER.

Application filed July 22,

To all 1071 cm. i/ m l/ concern.-

Be it known that we, Aneinn MONROE Fon'rn and \l'ihttirtt CALVIN Dnamcitizens of the l'nited States, residing at Ballinger, in the county of ltnnnels and. State of Texas, have invented certain new and useful Improvements in Scrapers, of which the following is a specification.

This invention relates to improvements in that type of scrapers which are commonly known as fork scrapers, and has for its objert to produce a device of this character \\'lll('lt, owing to its peculiar construction, has a very wide range of usefulness.

The essential feature of the invention resides in the provision of a skeleton scra or with a removable lining or bottom. T 'llS has the advantage of enabling the scraper to be used in soft and sandy soils, as well as the heavier soils. Y

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for ell'ecting the result-reference is to be had to the following description and. accompanying drawings, in which Figure l is a perspective view of my improved scraper and shows the removable;

bottom or lining in position. Fig. 2 is a perspective view of the removable bottom. Fig. 3 is a similar view of the skeleton. frame.

florrespontling and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters. r The skeleton frame of the scraper coniprises the usual bottom, sides, and end, the

bottom and sides being composed or a series ol' hvngitudinally-disposed teeth or tines connected near the forward end by a transverselywxtending U-shaped bar 2, while the end of the scraper is formed by bending the rear ends of the bottom lines upward and connecting them to transverse rods Z5, which join opposite and corresponding side tines 1. It will be observed that the rear end of the lowermost side tines 1 are simply bent around and secured to upturned ends of the Specification of Letters Patent Patented May 1, 1906.

i adjacent bottom tines 1 and are not con deleted by a cross-bar 3. Handles 4 extend upwardly and rearwardly from theskeleton frame and are secured thereto by inserting their ends into sockets formed by pieces of metal 5, which are secured to the two uppermost side tines 1. The U-shaped yokcfi has its arms pivotally connected to the forward end of the scraper and is provided with a draft hook or eye 7, which is swiveled there in. This skeleton framework will be found to give most satisfactory results in heavy soils and owing to its elasticity is frequently more eflicient than the solid or vmore rigid type of scraper in general use. I'lowever, it could not be used in soft or sandy soils, and for this purpose the removable lining or bottom is has been devised. This removable bottom 8 fits within the skeleton framework 1 in the rear of the cross-bar 2 and is formed with a bottom, sides, and ends corresponding to those of the scraper. In order to prevent accidental displacement of the bottom 8, spring-tongues 9 are bent outwardly from its edges and are adapted to engage with the crossbar Z, the uppermost side tines, and the to cross-bar 3 on the end/ of the scraper. It wi 1 thus be understood that the scraper can be used either with or without the lining 8, according to the character of the work to be done and of the soil to be excavated, and is therefore capable of giving the most ellicient service under all conditions of use.

claimed as new is 1. Thecombination of a scraper and a removable bottom or lining therefor.

K 2. The combination of a scraper, a removt able bottom or lining therefor and means for holding the removable bottom or lining in position.
